I watched Raiders of the Lost Ark last night as well as LOTR and I must say that the VPM144 or the VPM194 is the way to go. I tried to distinguish between these 2 setups and about the only difference I could come up with is that the VP150 adds a bit of extra warmth/fullness to the center channel. I noticed no phasing as Mojo and I did with just the dual M22's during the LOTR Narration at the beginning of the movie.

Alas I didn't find my SPL meter either so I cannot confirm how much extra SPL this configuration gives over dual or single center channels. Maybe today.

My little Denon 1804 cranked out the sound with out any trouble at all. I unplugged my sub during LOTR, as the dynamics in that movie are off the scale and it was getting close to 2AM, I didn't want to wake everyone up. The M60's did a great job with the explosions even with the Mains still set to no LFE and crossover at 80hz
